Stowing luggage on the Shinkansen (Japanese Bullet Train) in 2026 involves following specific rules based on the size of your bags. For small to medium items, there are overhead racks that run the length of the car; these are surprisingly deep and can accommodate most standard "carry-on" sized suitcases. If you have "oversized" luggage (where the total dimensions of length + width + height exceed 160cm but are less than 250cm), you are required to make a reservation for a seat with a "large luggage area." This area is typically located in the space directly behind the last row of seats in a car. When you book this specific seat, the luggage space is included for free. If you show up with large bags without a reservation, you may be charged a fee of 1,000 yen and be asked to move your bags. For extremely large items or for travelers who want a hands-free experience, the "Takkyubin" (luggage delivery service) remains the gold standard, allowing you to ship your bags from your hotel in one city to your hotel in the next for a very reasonable fee, usually arriving the following morning.
